The Study And Applications Of Control System Of Cars' Window Lift Motor Production Line

This thesis is aiming at research of control system of window lift motor assembly line which is a part of automotive component manufacturing. Through the research and application of assembly line control technology, the manufacturing technology and competitiveness of the enterprise will be shifted significantly.The technical improvement and application of window lift motor assembly line control system refer to the application of modern technical achievements and advanced experience to improve the automatic control technology of automotive component industry. The enterprise launches advanced electric and communication technology based on the actual demands and continuously upgrades the traditional manufacturing equipment at the same time. Such kind of upgrading will improve the efficiency of the original manufacturing system and reduce the energy consumption, in parallel the down time will be minimized. It's regarded as a key measure for expansion and reflects the combination of modern science and technology for automotive component industry.The thesis will focus on research of control system of window lift motor application of PLC technology and profibus technology on motor assembly line. Window lift motor assembly line is consisting of more than a dozen work stations, each work station is controlled by profibus technology and PLC combined with servo motor control, interface, welding, screwing and various sensor detection technologies.Window lift motor is made up by kinds of components, the motor is assembled with assistance of equipment with different functions by defined working processes and control requirements. In the whole course of research, advanced control technology will help to solve the problems like low efficiency, unstable quality, poor reliability, long change-over time and etc, at the same time, the manufacturing equipment must be running in a stable and efficient way and be able to perform simultaneous control of process parameters to meet the strict requirement defined by manufacturing process for quick and accurate assembly.
